Improvement in seed-drills



UNITED STATES JACOBr STEAYEE, OEMIAMISBUEG, OHIO.

IMPROVEMENT I N SEED-Deuts.

Specification forming part of Letters Patent No. 32,319, dated May `14,1861.

To all whom fit may concern:

Be it known that I, JACOB STRAYR, of

Miamisburg, Montgomery county, and State of Ohio, have invented certainnew and useful Improvements in Seed-'Drills 5 and Idohereby declare thatthe same are described and reproller opposite the spaces on-the otherpart orA portion of the roller, so as to discharge or deliver theseedmore uniformly.

Toenable others' skilled in the art to make -and use my improvements, Iwill proceed to describe their construction andoperation, refering tothe drawings, in which the same letters indicate like parts in each ofthe figures.

Figure l is 'a plan or top view of the feeding-roller in its case. Fig.2 is a side elevation ofthe same. Fig. 8 is a section on the line z e,Fig. l. Figfd is an elevation of one end. y

In these drawings A is a cast-metal box, made in the form shown in thedrawings, and provided with screw-holes B B, for the screws which fastenit to the bottom of the seed-box. This seed-box A has a cavity, C, intheupper side to receive the Seed which fallsinto it from the seed-box, andtheuseed is carried forward by the teethD D ot' the feeding-roller,which turns in the box or cavity C until it the seed) falls out of theopening E (shown in Fig. 4) into the delivering-tube hung below oraround the opening. The teeth D D of the feeding- Vroller are madeone-half the length of the roller, and so Varranged that the teeth onone part come opposite the spaces on the other A part, as shown in Figs.l and 3'of the drawings. This is a very great and very importantadvantage, as it feeds or delivers the grain far more uniformly than ifthe teeth extended entirely across the roller, and this is the greatadvantage my improvement has over the feed y ing-rollersl heretoforeused, which delivered the grain in parcels. y I

F is the shaft of the feeding-roller. It turns in the scores Gr Gr inthe box A, which are tted to receive the shaft, which is connected tothe carrying-wheel of the drill, so as to be turned by it.

The scores G G are closed by the caps H H, titted to them, which capsare connectedby the bridge I, as shown in Fig. l)l vThere is a recessin-the top of the box A (shown by the lines J J) for a slide to cut oft`the supply of seed. In Fig. 3 a section of the bottom of the seed-box isshown at K K, and theslide to shut the seed from the roller'at I..

The feed-roller that I have described is made straight on the surface,or of a uniform size from end to end; but in feeding some kinds of grainit is preferable to make the roller spherical or spheroidahas shown inFig. 5. When made in this way the roller carries or feeds most of thegrain in the center, and by making the teeth on the roller spiral theyrun the grain toward the center as it is delivered, which is a greatadvantage. When the feeding-roller is made spherical or spheriodal thecavity in thebox A should be made hemispherical to correspond with theroller.

I believe I have described my improvements in feeding-rollersforseed-drills so as to enable any person skilled in the art to make anduse them. I

I will now state what I desire to secure by Letters Patent, to wit:

Making the teeth on one part or portion of the feeding-roller forseed-drills opposite the spaces between the teeth on theother part orPportion of said roller, substantially as described, so as to deliver ordischarge the seed more uniformly.
